When high, the receiver driver gain is set to -6 dB, with sidetone.
When low, the receiver driver gain is set to 0 dB, with no sidetone.
When high the received PCM stream is interrupted and replaced with quiet code; thus forcing the receive path into a
When high, the FDI PLA and the Filter/Codec are powered down. When low, the FDI is active (default).
When high, the ear driver and Filter/Codec are powered down. In addition, in ST-BUS mode, the selected output
